In reply to wintertree:
> Do you have 63 square meters of roof? Is it all South facing?
Yes, but as you say it's not common. Plus, if the UK wanted to take it seriously, planning regs should have been encouraging North / South aligned housing/roofs for the past decade.
> Don't forget California has less clouds, more sun, more consistent summer/winter sun (this is a battery for a day, not half a year) and that people tend to have bigger roofs and that there is heaps of underused scrubland calling out for solar PV.
It's a battery back up for silicon valley geeks so they can keep playing minecraft or update their social status even when the power blacks out for a few hours.
> deep cycle
Exactly, deep cycle has hardly news, most people know them as leisure batteries already.
> . Other than actually funding fusion research properly... To any nation not governed by simpering moronity and short termism this would be funded as THE national priority, not unlike the Manhattan project or the Apollo missions.
The first country to implement this will have won the power generation lottery forever, their global competitiveness in industry would be huge, just look at the boost the USA got from cheaper power through shales and fracking. It's madness not to be pushing forwards. Certainly a higher priority than landing back on the moon or going to Mars etc.
